Continuous steam sterilization segmented-flow aseptic processing produced shelf stable aseptically processed mushrooms of superior quality to conventionally canned mushrooms. ![]() Segmented-flow technology produced a narrower residence time distribution than pipe-flow aseptic processing thus, whole and sliced mushrooms were processed only as long as needed to achieve the target Fâ‚€  = 7.0 min and were not overcooked. The system utilized pressurized steam as the heating medium to achieve high temperature-short time processing conditions with high and uniform heat transfer that will enable static temperature penetration studies for process development. A pilot-scale continuous steam sterilization unit capable of producing shelf stable aseptically processed whole and sliced mushrooms was developed. This study was carried out to investigate segmented-flow aseptic processing of particle foods. Quality comparison of continuous steam sterilization segmented-flow aseptic processing versus conventional canning of whole and sliced mushrooms. E., Jr.Ĭontinuous sterilization of plumbing, such as in hospitals, clinics, and biological testing laboratories is possible with ethylene oxide/Freon 12 (ETO/F-12) humidifier developed for sterilization of potable water systems. PMID:16496186Ĭontinuous sterilization of plumbing systemsīryan, C. Differences between design and observed temperature, pressure, and other profiles were quantified and investigated. Sterilizer performance also was characterized over the expected range of operating conditions. ![]() Examples of enhancements adopted include sanitary heat exchanger (HEX) design, incorporation of a “flash†cooling HEX, on-line calculation of Fo and Ro, and use of field I/O modules located near the vessel to permit low-cost addition of new instrumentation. In addition, the reasoning behind selection of some of these improved features has been incorporated. Design strategies of this new continuous sterilizer system and the expanded control system are described and compared with the literature (including dairy and bio-waste inactivation applications) and the weaknesses of the prior installation for expected effectiveness. This new equipment was retrofitted into an industrial research fermentation pilot plant, designed and constructed in the early 1980s. An existing Honeywell Total Distributed Control 3000-based control system was extended using redundant High performance Process Manager controllers for 98 I/O (input/output) points. Nuechterlein, J.Ī new continuous sterilization system was designed, constructed, started up, and qualified for media sterilization for secondary metabolite cultivations, bioconversions, and enzyme production. A next generation, pilot-scale continuous sterilization system for fermentation media
